That's for compressed kernel and initrd. I wanted to compare apples to apples. You can put an uncompressed kernel and ROM file system in the Flash. Just copy the kernel (or kernel data) to RAM and you are all set. That should boot pretty fast. The trouble with using Linux is you have lots of choices. You actually have to _think_ about which is best for you and how you want to implement the solution. I don't particularly like other software packages that proclaim "we did it for you", hide the code in a binary somewhere, and you spend your time working around their rules. With all of the GUIs and "click here to make it happen", people have forgotten (or never learned) to think for themselves. I have yet to find a (reasonable) product requirement that can't be solved with Linux. I implement what is useful to me and my customers. If you want something else, and it isn't there, just do it. I'm not going to guess at what you may want. My challenges have been systems with lots of RAM and not much Flash ROM. If you can actually purchase the flash ROM and are happy with the high prices, go ahead and load it up.
